# SmartRIBBON™ OFNR Listed Indoor/Outdoor Optical Fibre Cable


OFNR-rated, FT4 compliant ribbon cable (144F–3456F) with intermittently bonded  ribbons and gel-free dielectric construction for high-density indoor/outdoor  applications.


Engineered to provide serious capacity through backbone and high-density networks, this SmartRIBBON™ cable features intermittently bonded 12F ribbons grouped in flexible buffer tubes. This design ensures dependable performance in aerial, duct, or indoor riser applications while remaining completely gel-free for fast and clean preparation.
The cable is rated OFNR (Riser) and also meets the FT4 vertical tray flame test, offering excellent flame-retardant properties and minimal fire propagation for safe transition between outdoor and indoor environments. With non-metallic FRP strength members for a dielectric construction and water-blocking yarns for full core protection, it is a dependable choice for data centre interconnects, campus backbones, and hyperscale infrastructure.
